John Carmack suggest that someone should write a engine in more functional way (with GC). So you would reconstruct all the objects given access to the last frame's memory, (which would immutable). Then run the GC between frames. This may cause problems if a slower computer never has time between frames to run GC. (Running at 27fps trying to reach 30fps, my old Laptop would do this most of the time)
